Can I use an N64 controller without an adapter?

[chris1970au]

Hi all, I'm using Project 64 and I want to use my N64 controller to play the roms, can anyone tell me how i can do this without buying an Adapter of any kind or taking the cover off my n64 controller, i'm thinking about cutting the n64 cord and attaching it to a USB connector, the problem i have with that is the n64 has only 3 wires, red, black and white and the USB cord has 5 wires, red, black, white, green and bare/ silver.... Please help!!!
Thanks in Advance

P.S. any N64 drivers out there for XP?
